Claude Code v2.1.198 の変更点

What's changed

• Claude in Chrome is now generally available

• Added background agent notifications in claude agents — sessions that need input or finish now fire the Notification hook (agent_needs_input / agent_completed)

• Added /dataviz skill for chart and dashboard design guidance with a runnable color-palette validator

• Gateway: added Claude Platform on AWS (anthropicAws) as an upstream provider; model-not-found responses now advance the failover chain

• Background agents launched from claude agents now commit, push, and open a draft PR when they finish code work in a worktree, instead of stopping to ask

• The built-in Explore agent now inherits the main session's model (capped at opus) instead of running on haiku

• Subagents and context compaction now inherit the session's extended thinking configuration, improving output quality on delegated tasks

• Fixed brief network drops mid-response aborting the turn — transient errors like ECONNRESET now retry with backoff instead of failing

• Fixed excessive background classifier requests when sandboxed processes repeatedly accessed the same network host

• Fixed background tasks in web, desktop, and VS Code task panels getting stuck on "Running" after they finish or after resuming a session

• Fixed agent teams: a teammate that dies on an API error now reports "failed" to the lead, and messaging a stuck teammate wakes it to retry immediately

• Fixed the /diff panel not refreshing when you switch branches or commit outside the session

• Fixed markdown tables overflowing and wrapping their right border when rendered in fullscreen mode

• Fixed Claude Platform on AWS and Mantle sessions dead-ending with "Please run /login" when the STS token expires — awsAuthRefresh now runs automatically

• Fixed "no route to host" for local-network hosts in macOS background agent sessions by declaring Local Network entitlements

• Fixed /desktop failing with "Cannot determine working directory" after entering and exiting a worktree

• Fixed background agents repeatedly showing "Reconnecting…" every ~52 seconds on macOS while the agents view was open

• Fixed pressing ← inside claude attach exiting to the shell instead of opening the agent view

• Fixed claude --bg silently creating an unattachable session when combined with --print/-p; the conflicting flags are now rejected up front

• Fixed the workflow progress view dropping the earliest agents from the list while the phase counter stayed correct in SDK and desktop-app sessions

• Fixed .claude/rules/ conditional rules not loading when the target file is reached via a symlinked path

• Fixed Cmd+click not opening URLs in fullscreen mode in Warp on macOS

• Fixed double-click word selection in fullscreen mode to select the entire URL including the scheme

• Fixed plan mode not auto-allowing read-only tool calls when a session starts in plan mode

• Fixed /branch deriving its default fork name from the compaction summary instead of the first real prompt

• Improved focus mode: subagents launched in a turn now appear in its activity summary, and completed background notifications fold into a single count

• Improved syntax highlighting accuracy in code blocks, diffs, and file previews by upgrading to highlight.js 11

• Keyboard shortcut hints now show opt/cmd instead of alt/super when connected from a Mac over SSH

• Improved API retry UX: the error reason is now shown after the second attempt, and a status page link replaces the spinner tip when the API is overloaded

• /login now opens the sign-in dialog from the claude agents view instead of saying it isn't available

• Subagents now treat messages from the agent that launched them as normal task direction; an agent's message is still never treated as the user's approval

• Removed the /agents wizard; ask Claude to create or manage subagents, or edit .claude/agents/ directly
